STOCK-FOOD STEAMER AND VEVAPORATOR.

SPECIFICATION forming part of Letters Patent No. 279,142, dated June 12,1883..

Application filed March12,1883. (N model.)

To all whom it may concern:

Be it known that we, CHARLES F. FARRAR,

of South Lyon, in the county of Oakland and .tical section, and Fig. isa sectional view of the side of the tank A and false bottom I)". Arepresents the tank in which the food is cooked. This tank is made ofwood, is constructed long and narrow, is lined with galvanized iron, andis made movable, so that it can be readily removed from its place overthe heating-chamber. At the bottom of this tank we construct a metallicwater-chamber, A the whole length of the tank. For ordinary pur poses wemake the tank A so' that it will hold about forty bushels of feed; butit often happens that for special occasions a much larger quantity isneeded, and to prepare for such cases we have provided for enlarging thetank A by the addition of a box, A. It is made of ordinary boards, andis made to fit closely 011 the edges of thetank A, and properly fastenedthereto, so that it will not readily slide off. This is done by thestandards 0 0, though other means may be devised for the same purpose.The lid A of the tank A will also do for a covering for theextension-box A.

in the cooking-tank A. These partitions,when

in place, serve to divide the tank into two or more compartments, andthe tank, as will readily be seen, is-thus easily made from one intoseveral cooking-chambers, so that while one kind of food is cooking inone chamber another kind may be cooking in another, and so on a thirdkind may be cooking in a third chamber. This division of thecooking-tank is of great utility when different kinds of stock are beingfed by the same person, for generally in such cases they feed differentkinds of food. As one kind of food will be easier cooked than anotherkind,the one done first can be easily re moved and the. others kept intill done.v The great utility of the division of the tank A will readilybe seen without further explanation. These partitions a a are put in bymeans of the V-shaped groove in the side of the tank, and

a corresponding V-shaped finish of the ends of the partitions a, andthey will be held down in place by pins, as seen at a in Fig. 1. c a arelegs of our furnace.

B is the combustion-chamber, and D D is the frame-work. The chamber B ismade nearly square, has a door, I), for charging in wood fuel, and hasalso the coaling-chute b. This latter has a damper to the lid, which isuseful to regulate draft over the fuel, to admit more or less of air, orto shut it off altogether, as required. I) is an ash-pan below the grateb". This grateb is made of a circular shape, and we make it this shapeso as to hold the, burning coals in a close, compact manner, thus makinga more perfect combustion, for air is thus admitted, not only from thebotton of the grate, but also from the sides thereof and also by thisshape of grate fire is kept from the walls of the furnace or chamber B,thus protecting them. The draft of the chamber B is along thesmoke-flue- B, the bottom of which flue B is made of boileriron, is asbroad as the combustionchamber, and extends the full length of the tankA. I11 order to get the fullest benefit or service from the flame, wemake this fine B fiat and wide, thus bringing the bottom of thewatertank A nearer the bottom of the flue B. In this way the heat is themost economically util ized. The smoke and waste heat pass off throughthe stack 0 in the direction of the arrow-points. h

In order to keep the food while cooking separated from the water in thechamber A we use the well-known device, a perforated false bottom, bmade of galvanized iron. tom 11 is made to lie flat lengthwise andacross the bottom of the tank A and a little above the water-line. Ithas adequate supports in Both are made of cast-iron This b'otthe center,resting on the bottom of the chamthe heat has full force byreason of ourfiat and wide flue B, thereby performing the work by the use of muchless fuel than is required in those furnaces that have smallheating-surfaces. By this large heating-surface in the flue B we cookthe food better by cooking it quicker, for the steam can be more rapidlygenerated, and also raised to a greater degree of heat on the samequantity of fuel. Although we do thus get up a higher degree of heat,there will be no danger of scorching. the. food, as the waterchamber Aintervenes, and also the bottom If. The water-chamber A has a capacityfor holding from twenty-five to thirty gallons of water, and this willoutlast the fuel necessary to cook the food, so that there is nodangerfrom lack of Water over the fire.

The tank A can be utilized for other purposes than simply the cooking ofanimal 'food as, for instance, in evaporating sugar-water or sorghum,making soap, boiling clothes, scalding hogs, washing sheep, 8m.

Through the faucet b boiling water may be run off for special uses whilethe cooking is going on, for draining the water from the chamber A, &c.

The rest for the bottom I) in the bottom of the chamber B, water is putinto the chamber A and when the articles to be cooked are in theirrespective compartments the lid A is placed on, so as to confine thesteam Within the tank A. When a larger bulk of food is to be cooked thanthe tank A will hold We put on the eXtra box A and place the lid A" ontop, as in the case before mentioned.

Having thus described our invention, what we claim, and desire to secureby Letters Patcut, is

1. In an animal-food steamer, a food-tank provided with removablepartitions, an extension, and a top, in combination with a watertanksituated beneath said feed-tank, a perfo rated removable bottom betweensaid tanks, and means for heating said Water-tank, substantially as andfor the purposes described.

2. The combination, in astock-food steamer and evaporator, of thecombustion-chamber B, having the circular grate b", coaling-chute b,damper I)", ash-pan b, flue B, tank A, perforated bottom I), andwater-chamber A, substantially as described, shown, and for the pur poseset forth.

In testimony Whereofwe hereto set our hands.
